Abstract
The utility model is related to a kind of EMUs sun-shading screen for driver cab synchronism mechanism, including left and right motor, left and right mechanical arm, lower fixed cover, it is characterised in that：It is coaxial and respectively set a synchronizing wheel on lower fixed cover with the end of left and right mechanical arm the latter half, take up two synchronizing wheels set one " compile 8 " steel wire rope.The outer free end of two mechanical arms is linked with steel wire rope, whole mechanism is become to the rock-steady structure of Three Degree Of Freedom by the unstable structure of six degree of freedom, when left and right motor action, cord stretching/withdrawal is driven by left and right mechanical arm, now lazy-tongs work, ensure six-bar linkage parallel motion so that realize and be synchronized with the movement in the free end of left and right mechanical arm；The rigidity of the lower fixed cover of increase；The fault tolerance of abat vent installation is added, the service life of abat vent is extended；Because this scheme change amount is small, effect is good, it is to avoid a series of drivers' cabs that the abat vent mechanism more renewed is brought are built-in plus change.
Description
Technical field
The utility model is related to railway vehicle cab abat vent, more particularly, to the synchronism mechanism of abat vent.
Background technology
The outer free end of two mechanical arms of abat vent of motor-car vehicle relies solely on the bullet of its own without related lazy-tongs
The flexible axle structure of spring and upper end realizes the synchronizing function of both sides mechanical arm, and the quality requirement of requirement and parts to assembling is all
It is very high.Symmetrical six-bar linkage structure centered on sun-shading screen for driver cab, is extremely difficult to both sides symmetrically during action, asymmetric caused
Consequence is exactly the two mechanical arm unbalance stress in left and right, once mechanical arm unbalance stress, the running orbit of cord will change,
Curtain phenomenon will be stung during action and then asynchronous, ultimately result in clamping stagnation operation not smooth.
The content of the invention
The purpose of this utility model is to increase a kind of lazy-tongs in original abat vent actuating mechanism so that in assembling
And use environment can not meet when its abat vent self-operating is balanced and help its corrective exercise state, make abat vent operationally
Synchronism stability is acted, extends its service life.
To realize above-mentioned utility model purpose, the utility model provides a kind of EMUs sun-shading screen for driver cab and is synchronized with the movement machine
Structure, including left and right motor, left and right mechanical arm, lower fixed cover, it is characterised in that：With the end of left and right mechanical arm the latter half
A synchronizing wheel respectively coaxially and on lower fixed cover is set, two synchronizing wheels is taken up and sets " a steel wire rope for volume 8 ".
It is located on described lower fixed cover on the inside of two synchronizing wheels and respectively sets a fixed plate, the outer gum cover of steel wire rope is fixed on fixation
On plate, convenient maintenance.
Advantage of the present utility model has：
1st, the outer free end of two mechanical arms is linked with steel wire rope, whole mechanism is become by the unstable structure of six degree of freedom
Into the rock-steady structure of Three Degree Of Freedom, when left and right motor action, cord stretching/withdrawal is driven by left and right mechanical arm, now
Lazy-tongs work, it is ensured that six-bar linkage parallel motion so that realize and be synchronized with the movement in the free end of left and right mechanical arm.
2nd, the rigidity of lower fixed cover is increased.
3rd, the fault tolerance of abat vent installation is added, the service life of abat vent is extended.
4th, because this scheme change amount is small, effect is good, it is to avoid a series of departments that the abat vent mechanism more renewed is brought
Dress adds and changed in machine room, directly saves the cost of overhaul and amounts to about more than 100 ten thousand yuan.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Reference picture 1, the utility model embodiment includes left and right motor 1,2, left and right mechanical arm 3,4, lower fixation
Cover 9, synchronizing wheel 5,6 is coaxial and under with the end of left and right mechanical arm the latter half under existing interface and running environment
A synchronizing wheel 5,6 is respectively set on fixed cover, two synchronizing wheels is taken up and sets " a steel wire rope 8 for volume 8 ".It is located at two together on lower fixed cover
Step wheel inner side respectively sets a fixed plate 7, and the outer gum cover of steel wire rope is fixed in fixed plate.The synchronous machine of 8 " compositions " is compiled by steel wire rope
Structure is attached under abat vent at fixed cover 9, and whole mechanism is become to the stabilization of Three Degree Of Freedom by the unstable structure of six degree of freedom
Structure, when left and right motor action, cord stretching/withdrawal is driven by left and right mechanical arm, now lazy-tongs work, protected
Demonstrate,prove six-bar linkage parallel motion.
During work, motor drives left and right mechanical arm to rotate when rotating, and left and right mechanical arm drives lower fixed cover to move up and down.
When not having synchronous mechanism for steel wire rope, due to left and right mechanical arm the latter half underconstrained, asynchrony phenomenon happens occasionally.Increase
After synchronous mechanism for steel wire rope, due to pining down for steel wire rope, left and right mechanical arm the latter half can be forced to be synchronized with the movement, it is final real
Now fix the balance movement of cover.Effect significantly, is greatly improved production efficiency, alleviates operator's labor intensity.
